C# 如何将桌面窗口保存为一半大小?
这是我现在使用的form1中的代码。 我每秒都用定时器捕捉桌面窗口。 最后我有一个按钮点击事件,如果我点击它,它将从所有保存的gif文件在我的硬盘上创建动画gif文件 但是,当我在internet explorer上加载/运行动画gif时,我在整个屏幕上看到的动画更大,因此每次我都需要使用并移动滚动条才能看到它 例如,如何保存桌面窗口的一半大小? 现在我的硬盘上有大约100个gif文件,每个文件大小为380-407kbC# 如何将桌面窗口保存为一半大小?,c#,.net,winforms,C#,.net,Winforms,这是我现在使用的form1中的代码。 我每秒都用定时器捕捉桌面窗口。 最后我有一个按钮点击事件,如果我点击它,它将从所有保存的gif文件在我的硬盘上创建动画gif文件 但是,当我在internet explorer上加载/运行动画gif时,我在整个屏幕上看到的动画更大,因此每次我都需要使用并移动滚动条才能看到它 例如,如何保存桌面窗口的一半大小? 现在我的硬盘上有大约100个gif文件,每个文件大小为380-407kb using System; using System.Collections

我想截取整个桌面窗口的屏幕截图,但在显示时,显示的窗口不会太大。您可以从这里更改大小
public static void screenshots(string filename)
{
//Create a new bitmap.
var bmpScreenshot = new Bitmap(
(Screen.PrimaryScreen.Bounds.Width - 100),
(Screen.PrimaryScreen.Bounds.Height - 100),

// other code
}
